Abstract

This research aims to study the effect of variations in preferences and feed on green flies by life phase variation of fish feed with different protein content. This study uses the control beef liver, tilapia fish, layang fish, milkfish, seluang and shrimp feed as a variation to test Preferences and Phase Living Green Flies. How to test for preference by releasing two hundred head of green flies in an enclosed space with a distance of 10 meters on the feed source of the cage flies, while the test phase Life by incorporating green flies 25 males and 5 females into the cage which contains 100g of feed resources in each cage rearing. Based on the results obtained in the preference test, variations of tilapia feed most preferred green flies with an average number of 50 flies and phase live green flies of egg to adult flies the layang fish and the tend to be longer in the media feed on fish seluang. green flies preferences influenced the overhaul of the resulting protein derivative composition of fish and shrimps, while the phase of life green flies influenced by the nutritional value of protein in fish feed resources
